, To all whom it may concern:

Be it known that we, THOMAS N. SoLoMoN and HARRY D. SOLOMON, citizens of the United States, residing at Detroit, in the production of a simple and efiicient means for controllingthe swinging of the dumping doors both to an open and a closed position.

With. these and other objects in view thisinvention consists of certain novel constructions, combinations and arrangements of 'parts as will be hereinafter fully described and claimed.

-'By referring to the drawings it will be seen that l designates the frame. of the car which is-provided with a centrally located longitudinally extending inverted substantially V-shaped rib 2, constituting the main floor of the can A longitudinally extending side plate 3 is secured near each lower side edge of said rib 2 by having the flange por tion 4 thereof fixed securely to the under face of the rib 2. Each side plate 3 is' provided with a laterally extending flange 5 to which flange is secured the transversely extending angle-irons or bars 6. These bars 6 carry brackets 7 which brackets 7 are pro vided with clamping members 8 formed of a plurality of sections, firmly held together by means of suitable bolts 9. 1

This sectional clamp 8 fits around aj ournal portion 10 carried by the door controlling or operating shaft 11, the shaft 11 being.

square in cross section. I v i A door 12 is carried below each side edge of therib 2 and is adapted to normally close the discharge opening formed along the side i of the car 1. Each door 12 comprises an elongated plate which is supportedupon the transversely extending angle bars 14. Thesev angle bars 14 extend through the apertures 15 formed in the side plates 3 and are pivotally mounted upon the supporting bnack .ets or cars 16 which are carried by the side plates 3. The inner ends of these angle bars 14 project inwardly toward the center of the for balancing the doors 12 and also for car and are adapted to constitute a means;

limiting the swing of the doors, should the inner ends of the angle bars 14 come in contact with the under face of the center rib 2.

The door controlling or operating shaft 11 carries an arm 17 which is connected to an angle plate 18, this plate 18 being connected to the outer end of one of the bars 14, ,as

shown clearly in Fig. 3. This angle plate is pivotally connected to the arm 17 by means of a pivot pin 19 and it will be seen thatthe flange portion 20 of the plate 18 will constitute a. means for limiting the swing of the plate 18 in one direction or while the door 12 Q j I is being swung to a closed position. As the r door is being swung to an open position, this plate 18 may easily swing upwardly with res ecttothe arm 17.

ach shaft 11 also carries aswingingarm link 22 is pivotally connected to the lower end of the hanger arm 23, the hanger arm 23 being pivotally connected upon the supporting plates 2%. These supporting plates 24 are secured to channel plates 25 carried by the longitudinally extending irons 26 carried by the body of the car. Each hanger arm 23 carries a link 27 which link is in turn connected to a depending eye 28 carried by the operating head 29. This head 29 is provided with projecting lips 30 upon each side thereof, which lips 30 fit between the guide bars 31 and are secured to the longitudinally extending channel irons 26 as shown clearly in Fig. 3 of the drawings,

A piston rod 32 is carried by the head 29 and this piston rod carries a. collar 33 and a collar 34, the collars 33 and 34 being spaced from each other to permit the piston rod 32 to have a suitable limited movement through the head 29 without moving the head. The lower end of this piston rod 32 carries a frame 35 which frame 35 is provided with plurality of rollers 36 and these rollers 36 engage. the beveled faces 37 of the latching bars 38. These latching bars orv arms 38 are provided with notches 39 TOTlllBdfl'lQlQlIl which notches are adapted to fit over the side edges T0 or" the head 29. it will be seen therefore that as the plunger rod 32 is moved downwardly, the rollers 36 will engage the beveled faces 37 and force the arms .38 outwardly thereby releasing the notches 39 from engagement with the head 29 as will be obvious by considering the drawings. As soon as the arms. 38 are released from the head 29, the collar 3l will engage the head 29 and permit the plunger rod 32 to move upwardly, the weight or" the ballast within the car forcing the door 12 downwardly and causingthe arms 17 and 21 to swing and thereby pushing the links 22 and 27 of the hanger arm 23 inwardly.

When it is desired to close the doors 12, the plunger rod 32 is forced outwardly by means of the structure hereinafter described thereby forcing the links 2? and 22 outwardly and swinging the hanger arms 23 as well as the arms 21 and 17 thereby swinging the doors 12 to a closed position. As the plunger rod 32 is moved or forced downwardly'the head 29 will fit into the notches 39 of the arms 38 due to the fact that these arms 38 are forced againstarms 29 by means of the spring pressed flanges e1 which are mounmd within the casing a2 suspended below the plates 43 carried by the longitudinally extending channel irons 26. These flanges 41 are provided with notches 4% within which notches the arms 33 fit.

By considering Fig. 6 it will be seen that the arms 38 are pivotally mounted upon the supporting brackets 45. A cylinder l6 is mounted below the rib 2 and upon the longitudinally extending channel iron 26 and this cylinder 16 carries a plunger head t? carried by the plunger rod 32. A cylinder head 4:8 is secured to the upper end of the cylinder lfi and the cylinder 46 is provided with a port 49 near this upper end carrying a ball valve 50 which is adapted to prevent air from passing down through the port 49 and at the same time permit air to pass upwardly through the port 1-9. The port 4:9 is provided with a discharge aperture 51 near the top of the cylinder and an intake aperture so as to permit the air to be forced from under the plunger head 47 and above the plunger head or piston head as soon as the plunger rod starts in its downward movement.

The cylinder l6 has a communicating pipe 53 communicating with the top plate 48 of the cylinder and this communicating pipe 53 as shown clearly in Fig. 2 communicates with the auxiliary or reservoir 54:. This reservoir 5% is also connected to a pipe 55 which pipe communicates with one end of the valve casing, the opposite end of the valve casing 56 communicating with a pipe 5? connected to a train pipe 58. The valve casing 55 carries a pipe 59 which pipe 59 communicates with the cylinder ll, as shown in Figs. l and 14 and this valve casing 56 carries a sliding valve 60 which sliding valve 60 is provided. with a circular passage 61 around the outer face thereof and near its lower end. As the valve 60 is raised to cause the exhaust port 62 of the casing 56 and the inlet port 63 to register with the channel or groove 61, it will be seen that theair may readily be passed out from the'cylinder 46 through the pipes 59, port 63, channel 61 and port 62. 'When the air is turned into the train pipe 58, the pressure forces the valve piston 60 to the opposite end of the valve thereby closing the port or channel 61. When the air is released from the train pipe the air premure from the auxiliary being greater, the valve piston is forced to the opposite end of the valve casing thereby opening the port 61 and permitting the air to escape into the atmosphere. W hen the piston has traveled down a full stroke, the air from the auxiliary may also escape throuih this port 62 as the piston 60 opens t e port 62.

As shown in Fig. 10 the piston rod 32 works through a packing 64 which packing supports or carries a leather cup washer 65. which fits snugly around the. piston memes closed position at the will of the person actuating the train pipe line. What is claimed is-: v
